Sid Manning e861d43f65 This change:
* Updates ReaderELF.cpp contentType method to match ELF.h's logic and now handle
    typeData
  * Add -arch to ldd-core testdriver
  * Add testcase to check typeData
  * Update others to stay in sync with this change.

Sid Manning dd11020739 This patch makes use of recently added relocation reference data. The bulk
of this is derived from the Mach-O writer.  Reviewed by: Nick Kledzik.
 * Adds loop to SectionChunk::write traverse references calling the
   writer's fixup handler, applyFixup.
 * Adds method, ELFWriter::buildAtomToAddressMap to that creates a
   mapping from an atom to its runtime address.
 * Adds method, ELFWriter::addressOfAtom to return the runtime address
   of the atom.

with subsequent changes to use lower level interfaces done by me.

Michael J. Spencer aedfa6a36b Fix MSVC compat. MSVC doesn't have bzero.
Although the code is not valid to begin with. It is trying to do a raw memory
copy of a non standard-layout type. nameoffset is not guaranteed to directly
follow cmdsize.

This should be properly fixed.

Nick Kledzik 7145cf6846 Add 'invalid' as a Reference Kind so that unknown/invalid kind strings can return that fact to the caller for use in constructing an error message, rather that triggering an assertion.

Nick Kledzik abb6981f68 Major refactoring: Remove Platform concept. In its place there are
now Reader and Writer subclasses for each file format.  Each Reader and
Writer subclass defines an "options" class which controls how that Reader
or Writer operates.
